Lazio is one of the 20 administrative regions of Italy. Situated in the central peninsular section of the country – the second most populated region of Italy (after Lombardy and just a little ahead of Campania). The capital of Lazio is Rome, which is also Italy's capital and the country's largest city.
The Italian word Lazio descends from the Latin word Latium. The name of the region also survives in the tribal designation of the ancient population of Latins, Latini in the Latin language spoken by them and passed on to the city-state of Ancient Rome. Although the demography of ancient Rome was multi-ethnic, including, for example, Etruscans, Sabines and other Italics besides the Latini, the latter were the dominant constituent.
